An Exploration of Outcomes Post-total Knee Arthroplasty in Middle East

The intention is to explore whether there are factors, which can help us to understand why some patient outcomes, following total knee arthroplasty are not successful and identify prediction factors for progression. Assessment of outcomes pre- and post-surgery with objective tools is a way to explore prediction tools for good/poor progression and improve patient selection and timing for surgery. The first aim of this project is determine the psychometric properties of the Arabic Version of Oxford Knee Score, including internal consistency, reliability and validity before and post-total knee arthroplasty in both males and females in a Middle East population. The second aim is to assess the reliability of the Star Excursion Balance Test for measuring the dynamic balance. The final aim is explore outcomes post-total knee arthroplasty among Middle East patients using the Arabic Version of Oxford Knee Score, physical activity measures and performance-based measurements such as: 30 s chair-stand test, stair-climb test, timed up-and-go test and a 6 m walk test while adhering to Osteoarthritis Research Society International recommendations.
